Abstract

A testing procedure is disclosed for testing a road tanker, and other transportable storage tanks, for fluid-tightness. A positive test pressure is first applied to one storage compartment of the road tanker, and simultaneously a negative pressure is applied to the outlet pipe of the storage compartment, and a different negative pressure is applied to the vapour recovery manifold. The subsequent pressure variations within the storage compartment, the outlet pipe, the vapour recovery manifold and the adjacent storage compartments are then monitored in order to determine whether the interconnecting valves are leaking, and whether the various compartments under test are fluid-tight. In a second stage of the testing procedure, the pressure within the storage compartment is raised in order to test the pressure release level of a pressure release valve in the storage compartment, and the pressure within the storage compartment is then reduced in order to test the vacuum pressure release level of the pressure release valve. Similar testing procedures are applied to each of the storage compartments in turn. <IMAGE>
